It finally hit me after watching old footage of Michigan players especially from the Bo-era, anyone in line play seemed to wear shoulder pads which looked about 4 feet wide. Obviously the current players wear versions which are just wide enough to cover their actual shoulders. Huge visual difference and it makes the old school guys look superhuman.
But...I don't know why the change. Was this a rule change that caused this across the board or is there some kind of a torque or leverage thing that is an advantage to be able to twist an opposing player out of the way? Watching other games we follow with basically everyone else in the country.
Just curious, not the most exciting topic but I felt that I needed to ask the intellectual depth of the Blog for answers!
